A man was shot and killed Tuesday evening in a drive-by shooting in Northeast Baltimore:

The 21-year-old victim was waiting at a bus stop with a woman on the 6600 block of Alta Ave. near the intersection with Northern Parkway, police said, when a four-door, light-colored vehicle approached and someone inside began firing a gun. Police were called to the scene about 6:30 p.m. and found the man lying in the street. The woman was uninjured.

Meanwhile, city police reported an arrest in another Northeast Baltimore shooting that occurred Monday afternoon. The shooting occurred about 3:15 p.m. in the 2700 block of Polk St., in the Coldstream-Homestead-Montebello neighborhood.

Also, Baltimore police over the past two days seized several guns from city streets, part of the commissioner's bad guys with guns campaign:

* A search of a house in the 3100 block of N. Woodington Road turned up a 9mm handgun and led to four arrests by the Southwestern District's drug squad.

* A search warrant served in the 3100 block of Belmont Ave. resulted in the seizure of a 12-gauge shotgun and one arrest by the Violent Crime Impact Division in the Western District.

* Police in the 700 block of Linnard St. in Southwest Baltimore arrested two people and seized a 9mm handgun.

* Another search warrant led police with the Gun Trace Task Force to the 3400 block of Callaway ave., where they seized a 12-gauge pistol-gripped shotgun.

* Police in Northwest Baltimore found four illegal long guns in a house in the 8500 block of Main Ave.
